Thanks for this magnificent book Andy, I had the intention to send you a note as you suggest at the end of PT&L (I like this name, as I’m a slow typing ;-) Bur today I reached page 256, and brought me right here. One of the things that has worked nicely with me is to draw mindmaps, both with the computer as well as on paper. Even I used the technique in an essay I wrote for a competition. The essay you can find it here:

Thanks again and looking forward to read more of your works. Greetings from Eindhoven, the Netherlands.

Hi! I will be teaching a group of High School students the fundamentals of software development and I want to use your book in the class. Do you have any guidance on how to best introduce the ideals in the book to that age group?

Probably the best thing to do is have everything set up for them in advance – Java installed, etc. The most questions and problems that come up seem to do with installing Java itself, and having the right versions of the MInecraft client and server software. Once that’s set up, then things are pretty straightforward.
